Don't use a strip-type thermometer, which you hold on your baby's forehead, to check your baby's temperature. Strip thermometers only show the temperature of your baby's skin, not her body. It's also best not to use an old-fashioned, mercury-in-glass thermometer.
If your prawns are smaller, spread a piece of aluminum foil or banana leaf on the grill first, then place prawns on top. Or skewer the shrimp with satay sticks (if wood, soak in water first). Baste the prawns the first time you turn them with a little of the leftover sauce. Grill 3 to 5 minutes each side. Prawns are done when the flesh turns from translucent to pinkish-white (and the shells turn a very attractive bright pink).
1 Lightly brush lemon wedges with some of remaining dressing and grill, turning over once, until grill marks appear, 3 to 5 minutes. Transfer to a large platter.  Grill shrimp on lightly oiled grill rack (covered only if using a gas grill), turning over once, until just cooked through, 7 to 8 minutes total.
